Intraprocedural CVC tip location in children
Background: Both intracavitary electrocardiography (IC-ECG) and ultrasound (US) have been proven to be safe and accurate for intraprocedural tip location during central venous catheterization, and both are known to be easily applicable and feasible in pediatric patients. Though, no prospective clinical study has directly compared the two methods as regards their applicability, feasibility, and procedural time.
Methods: This study prospectively enrolled all children requiring a central venous access device in non-emergency situations, during a period of 1 year. All devices were inserted according to a well-defined insertion bundle including both IC-ECG and US-based tip location. The primary endpoint of the study was to compare the two methods in terms of applicability, feasibility and time required.
Results: This study included 100 consecutive central venous catheterizations in children of age ranging from 1 month to 18 years. The applicability of IC-ECG based tip location was 98% and its feasibility 100%; the time required for IC-ECG was 1.9 ± 2 min. The applicability of US-based tip location was 96% and its feasibility was 100%; the maneuver required 2.2 ± 3 min.
Conclusions: US is an appropriate alternative method for intraprocedural tip location in children. The combined use of US and IC-ECG (both maneuvers being accurate, inexpensive, cost-effective, non-invasive, and equally fast to perform) should be recommended for tip location in pediatric patients, and it will avoid completely the use of fluoroscopy or of post-procedural x-ray.
